AUSTRALIA’S ENERGY MARKET IS IN TRANSITION
The Australian Energy Market Operator’s (AEMO) 2020 Integrated System Plan (ISP) was released in July 2020 and identifies nationally
significant and essential investments in the electricity system and outlines the forecast installed capacity requirements for generation

                    Key market requirements in the 2020 ISP(1)                Networks are critical enablers of the market’s transition

  • Around 18 transmission projects including 10 in NSW,
    representing direct opportunities for TransGrid with a combined
    estimated capital cost of approximately $13bn(2)

  • Targeted grid investment needed to balance resources across
    States and unlock Renewable Energy Zones (REZs)

  • Over 26 GW of new grid-scale renewables is needed to replace
    approximately 15 GW or 63% of Australia’s coal-fired generation
    by 2040

  • 6-19 GW of new dispatchable resources are needed in support
    to firm up the inherently variable nature of distributed and large-
    scale renewable generation

  • Rooftop solar expected to more than double (to ~25 GW),
    supplying up to 22% of total energy by 2040                                         Transmission                        Distribution

TRANSGRID – CHANGE OF SECURITYHOLDERS
Market valuations still do not reflect Spark Infrastructure’s 15.01%

  Wren House                             • Spark Infrastructure notes the completion of the sale process for the 19.99% stake in TransGrid held by Wren House to OMERS of Canada
  Infrastructure (WHI)
  stake sold to Ontario                  • The process to sell WHI stake in TransGrid commenced in early 2020 and was offered to Spark Infrastructure and other securityholders in
  Municipal Employees                      accordance with the pre-emptive process under the Securityholders Deed
  Retirement System
  (OMERS)                                • Spark Infrastructure declined to participate and notes that its 15.01% equity investment in TransGrid was purchased for $734.3 million in
                                           December 2015

                                         • The implied equity value on a proportional basis represents an approximate compound annual increase of 4.0% p.a. in addition to an
                                           approximate average distribution yield of 4.6% p.a. reflecting the improved business performance, growth in regulated and contracted
                                           assets (RCAB) as well as the anticipated significant and attractive growth pipeline

                                         • The valuation acknowledges TransGrid’s high quality business and once in a generation RAB and contracted growth pipeline
  Valuation reflects                     • Regulated asset transactions have averaged an EV / RAB of 1.40x since 2007
  RAB and CAB growth
  emanating from ISP                     • Pipeline of growth opportunities is expected to double TransGrid’s RAB in the current decade, assuming all ISP projects receive regulatory
                                           approval and proceed

                                         • CAB is a material component of the EV; CAB is currently $728m (growth of 43.2% in last 12 months); continued growth in CAB expected to
                                           be driven by connections of new large-scale renewable projects

                                         • Including CAB and valuing growth in RAB and CAB substantially adds to the headline RAB premium
